No sound on 8330

HELP! I have had the curve for three months and in the last week or so it has stopped ringing and notifing me of emails, texts, alarms, and calls.
I have done the following:
battery pulls
edited notification profiles using advanced (all on high not mute)
edited the exception list
removed last app (QuickPUll) added
When I do a battery pull it will sound once (call, email, or alarm) which ever is first
The speakerphone works during a call and I use it often
When I go into BB Alarms Pro and test the alarm sound it will not sound.
THe phone does vibrate when someone calls or I get a text. That is the only way I know someone is calling.

Please help this is driving me nuts and I am missing important calls.
Thank you :)
